G Finned Tube: An Efficient Solution for High-Temperature Applications

Product Overview

The G Fin Tube, also known as the Embedded Fin Tube, is highly regarded for its performance in high-temperature and moderate-corrosion environments. This innovative design enhances heat transfer efficiency, making it ideal for demanding industrial applications.

Manufacturing Process

The unique construction of the G Fin Tube involves creating a helical groove on the base tube, inserting the fin strip under tension, and backfilling to secure the fin firmly. This continuous and precise process results in superior bonding between the fin and the tube, optimizing heat transfer capabilities.

Materials Used

• Fin Material: Typically made of Aluminum (Grades: ASTM B209 Al 1060, Al 1100, A1050).
• Tube Material: Offers versatility with options such as carbon steels (e.g., ASTM A179, St 35.8), low-alloy steels, stainless steels, copper-nickel alloys, aluminum bronze, and nickel alloys (e.g., Alloy 400).

Key Features and Specifications

• Core Tube Options: Various materials including carbon steels and alloys.
• Maximum Operating Temperature: 450°C, suitable for rigorous thermal conditions.
• Dimensions:
  • Tube Outer Diameter (OD): 19 to 51 mm (3/8” to 2”)
  • Tube Wall Thickness: 2.11 to 3.5 mm (0.083” to 0.138”)
  • Tube Length: Up to 18,500 mm (60.7 ft)
  • Fin Thickness: 0.3 to 0.5 mm (0.012” to 0.02”)
  • Fin Height: 10 to 16 mm (0.394” to 0.63”)
  • Fin Pitch: 3 to 11 fins per inch (FPI)

Applications

G Finned Tubes are extensively used across industries such as petrochemical, power, paper, tobacco, and food production, especially in air coolers and heaters. The robust design supports maximum operating temperatures up to 400°C, making it optimal for systems requiring resistance to thermal shock and high-temperature conditions.

With its advanced slotting and embedding technology, the G Fin Tube offers reliable performance and durability in critical applications. Its heat resistance, versatility in material selection, and strong adherence ensure it meets the demands of modern industrial operations effectively.
